JLSEC-2026-691 A stack buffer overflow vulnerability exists in wolfSSL's PKCS7 SignedData encoding functionality

A stack buffer overflow vulnerability exists in wolfSSL's PKCS7 SignedData encoding functionality. In wcPKCS7BuildSignedAttributes, when adding custom signed attributes, the code passes an incorrect capacity value esd-signedAttribsCount to EncodeAttributes instead of the remaining available space...

JLSEC-2026-719

A stack buffer overflow exists in wolfSSL's PKCS7 implementation in the wcPKCS7DecryptOri function in wolfcrypt/src/pkcs7.c. When processing a CMS EnvelopedData message containing an OtherRecipientInfo ORI recipient, the function copies an ASN.1-parsed OID into a fixed 32-byte stack buffer...

Two buffer overflow vulnerabilities existed in the wolfSSL CRL parser when parsing CRL numbers: a heap-based buffer overflow could occur when improperly storing the CRL number as a hexadecimal string, and a stack-based overflow for sufficiently sized CRL numbers. With appropriately crafted CRLs,...

JLSEC-2026-711 Stack Buffer Overflow in `wc_HpkeLabeledExtract` via Oversized ECH Config

Stack Buffer Overflow in wcHpkeLabeledExtract via Oversized ECH Config. A vulnerability existed in wolfSSL 5.8.4 ECH Encrypted Client Hello support, where a maliciously crafted ECH config could cause a stack buffer overflow on the client side, leading to potential remote execution and client...

capstone: Capstone: Memory corruption via unchecked vsnprintf return

A flaw was found in Capstone, a disassembly framework. An unchecked return value from vsnprintf within the SStreamconcat function allows a malicious input to manipulate the internal stream index. This can lead to a stack buffer underflow or overflow, potentially enabling a local attacker to achie...

CVE-2026-47477

NVIDIA Triton Inference Server for Linux contains a vulnerability where an attacker can cause a stack-based buffer overflow. A successful exploit of this vulnerability might lead to denial of service...

CVE-2026-45133

Symfony is a PHP framework for web and console applications and a set of reusable PHP components. Prior to 5.4.52, 6.4.40, 7.4.12, and 8.0.12, when the parser is exposed to attacker-controlled input, deeply nested mappings or sequences cause both the block-level Parser::parseBlock and inline...

CVE-2026-45133

CVE-2026-45133 affects Symfony YAML parsing: when fed attacker-controlled input, deeply nested mappings/sequences can cause unbounded recursion in both Parser::parseBlock() and Inline::parseSequence()/Inline::parseMapping(), exhausting PHP stack and crashing workers. Affected versions include Sym...
